MATLAB® Interface for AWS S3™

This is a MATLAB® interface for the Amazon Web Services S3™ service. This is a low-level, general interface that can be customized if the higher-level interface as provided in MATLAB does not support your needs. see here for more details on what is provided in MATLAB.

To build a required JAR file:

Getting Started

Please refer to the Documentation to get started. The Installation Instructions and Getting Started documents provide detailed instructions on setting up and using the interface. The easiest way to fetch this repo and all required dependencies is to clone the top-level repository using:

git clone --recursive

Build the AWS SDK for Java components

The MATLAB code uses the AWS SDK for Java and can be built using:

cd Software/Java
mvn clean package

Once built, use the /Software/MATLAB/startup.m function to initialize the interface which will use the AWS Credentials Provider Chain to authenticate. Please see the relevant documentation on how to specify the credentials.

Create a bucket, list existing buckets, upload and download objects

%% Create and initialize a client
s3 = aws.s3.Client();

%% Create a test bucket
bucketName = 'com-myorg-my-test-bucket';

%% List existing buckets
bucketList = s3.listBuckets()

%% Upload a file
% Create some random data
x = rand(100,100);

% Save the data to a file
uploadfile = [tempname,'.mat'];
save(uploadfile, 'x');

% Put the .MAT file into an S3 object called 'myobjectkey' in the bucket
s3.putObject(bucketName, uploadfile, 'myobjectkey');

% Download a file

% Delete a object and then the bucket

% Delete the client

The interface supports a number of S3 features including credential-free authentication using IAM when running on EC2™. Please consult the documentation for more details.
